PROBLEM TO BE SOLVED: To obtain an improved head drum assembly in which the assembly process in much more simplified so as to improve the productivity and number of components is decreased to attain a simpler structure. SOLUTION: The head drum assembly 100 has a rotary drum 10 and a stator drum 20, the rotary drum 10 is made up of a base plate 11 and a cylindrical wall 12, a video head 50 is fixed to an upper face 17 of a base plate 11 and a rotor transformer 70 is provided to a lower face 18. A receiving hole 16 in which a rotary shaft 30 is press-fit and received is made at the center, the cylindrical wall 12 is extended upward from the circumferential edge of the base plate 11 and a head window 19 notched to expose the video head 50 externally is formed in the lower part. |
